I use those fake vines on occation, especially with deremensis or baby veields. However, I wouldnt' use them with adult veileds, or melleri, or any veggie-nibbling species.
I bought a subadult female from a breeder that used them. She stopped eating a few weeks after I got her, and died a couple months later. Her stomach was packed full of the things. Swollen aboout the size of a golf ball.
